The XRAY 362370 composite inline hub helps tuners set correct bevel gear position on XB4'21 cars for smoother power delivery. By fine tuning alignment and height you can reduce drivetrain stress and improve handling predictability.
Made for installation at the rear HS bulkhead of the XB4'21, the composite hub offers six selectable heights allowing a 5mm adjustment window. These choices give control over rear roll and traction characteristics when experimenting with setup changes.
Intended for the XRAY XB4'21 series, the hub is suitable for racers testing setup changes between surfaces. Correct setup improves gear mesh consistency and lowers the chance of binding under load.
